LM4953 Ground-Referenced Ultra Low Noise / Ceramic Speaker Driver

The LM4953 is an audio power amplifier designed for driving Ceramic Speaker in portable applications. When powered by a 3.6V supply, it is capable of forcing 12.6Vpp across a 2µF + 30Ω bridge-tied-load (BTL) with less than 1% THD+N. Boomer audio power amplifiers were designed specifically to provide.

LM4953 Features

* a low-power consumption shutdown mode. Additionally, the LM4953 features an internal thermal shutdown protection mechanism. The LM4953 contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions. The LM4953 is unity-gain stable a
